The vacuum machine is simple in structure, small in size, convenient for use, highly flexible and suitable for zipper bags of different sizes and types. It not only vacuumes zipper bags, but also securely seals the zipping strips of zipper bags, thereby solving the problem of difficulty in sealing the zipping strips accurately.
